Commentary
Adapter for DYNACo 4-channel system.
You can enjoy 4-channel performance by simply connecting the QD-1 to the output terminal of the 2-channel stereo amplifier while using the source and 2-channel stereo amplifier.
Two channels of sound are output from the front, and the difference signal component is reproduced from the rear.
Since there is a 2-channel and 4-channel changeover switch, if the rear signal is turned off, normal 2-channel playback will be performed.
